Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Beyond the annotations (readOnly, idempotent, openWorld, non-destructive), the description discloses the beta status, the fact that no candidate is currently active so it exactly matches ask_pipeworx, and that it does not fall back to anything — it is a full working router. This is rich, accurate behavioral context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Four sentences, each adding distinct value: what it is, current state, how to use it, and what it is not. No filler or repetition; the most important scoping information appears first.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given annotations cover safety and the schema covers parameters, the description supplies the critical context: relationship to ask_pipeworx, current experimental state, and full functionality. It is almost complete, though a one-line note on what kind of answers or routing behavior to expect would make it fully self-contained for an agent unfamiliar with ask_pipeworx.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents the question parameter and its aliases. The description says 'same arguments' but does not add per-parameter meaning, so the baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly identifies the tool as a beta universal router that mirrors ask_pipeworx, with the same 5,767 tools, arguments, and response shape, and explicitly frames it as the experimental edge. This distinguishes it from the stable sibling ask_pipeworx and prevents confusion with ask_pipeworx_grounded.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives an explicit usage condition: use it exactly like ask_pipeworx when you want the newest routing, and notes results are compared against the stable router. It stops short of stating when-not-to-use, such as choosing stable ask_pipeworx for production needs, so it is clear but not fully exclusionary.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
